This is a navy track jacket with a layered collar. There is no material tag, but it appears to be a cotton-polyester blend, similar to sweatshirt material. The collar has a layered look, with a gray heathered cotton inner layer and a stand-up collar (13cm high). The stand-up collar has a zipper that can be opened, but there is no hood inside. The front opens and closes with a zipper. There are pockets with flaps (with buttons) on both sides. The inside is lightly brushed. The size is indicated as L, but it is small. Actual measurements: Shoulder width: 42cm Pit to pit: 46cm Hem width: 46cm Sleeve length: 62cm Length: 63cm (excluding collar) It seems to be equivalent to a size S. There are no noticeable pills or stains on the surface, but there is some slight staining on the inside of the sleeves. #TrackJacket #Sweatshirt
